Research interests
-
Food materials sciences
The characterisation and implementation of food macromolecules for use as natural texture modifiers, stabilisers and emulsifiers.
-
Flavour chemistry
Exploring the chemical compounds responsible for the taste and aroma of food, investigating how factors like ingredients, processing, and environment influence sensory experiences and consumer preferences.
Research impacts
Thomas' research bridges traditional Indigenous food knowledge with modern science, focusing on sustainable, health-conscious ingredients from native Australian plants. It contributes to the food industry by developing natural colourants and bioactive compounds, promotes cultural preservation, and supports eco-friendly practices, offering both economic and societal benefits through industry partnerships and Indigenous collaborations.
